IMPROVEMENT IN APPARATUS FOR CUTTING AND ORNAMENTING SHOE-UPPERS.

Specification forming part of Letters Patent No. 180,672, dated August1, 1876; application filed June 20, 1876.

To all whom it may concern Be it known that I, EDWIN B. STI PsoN, of:Brooklyn, in the county of Kings and State of New York, have invented anew and useful Improvement in Presses for Cutting and Punching Boot andShoe Uppers, of which the following is a specification My inventionrelates tomachines'for cutting out and punching fancy designs on bootand shoe uppers, which consist essentially of a series of small punches,one or more large punches, a bed-die, and a stripper, contrived in theordinary way of punching-machines, for making ornamental figures in theuppers of shoes; and it consists of the steel die-plate riveted to aniron plate, the object of which is to combine with the die-plate asufficient. body of metal, that will not crack in cooling, to preventthe dieplate from cracking, to which it is so liable in hardening, owingto the irregular, and, in some places, narrow parts of the metal.

It also consists of the stripper suspended from the head of the press bysprings to raise it out of the way of handling the goods after the goodsare out, the stripper being fixed on guides which keep it in its properposition. It also consists of a marking-plate, having small points formarking imitation stitches, or other ornamental design attached to theunder side of the stripper-plate for being operated by it.

It also consists of the broad punches for cutting out long strips madeconcave on the cutting end, whereby they project more at the oppositesides, and shear-cut the goods from both ends of the long slots to thecenter, whereby they not only cut easier, but they hold the goods intheir position on the die, instead of forcing them to one side.

Figure 1 is a side elevation of my improved machine. Fig. 2 is a sectionthrough one of the large punches, taken on line as :r, Fig. 5. Fig. 3 isa section of the stripper. Fig. 4 is a section of the bed-die. Fig. 5 isa plan of the stripper; and Fig. 6 is a plan of the beddie.

Similar letters of reference indicate corresponding parts.

A is the bed-die, having the large openings B and smaller ones 0, D, E,and F, for which there are corresponding punches or cutters in themovable head G of the pressfor cutting out ornamental figures in v theleather uppers for shoes. This die-plate is riveted to an iron bedpiece, H, of corresponding shape, and having similar openings throughit, said iron plate being to hold the heat, and also to hold the steeldie-plate, so as not to break when hardening the die. J is the stripperfor stripping the work ofi the punches. It is suspended from thepress-head K by the arms L, guide-rods M, and springs N, so that it canrise a certain distance above the bed-die when the punches rise, andthus be out of the way of adjusting the Work under the punches.

The springs N allow the head G to press the stripper down when it goesdown to drive the punches, and the arms L stop it when it has raised ashigh as desired, to allow the punches to rise up into it, so that it canstrip 0d the goods.

0 represents the marking-plate, attached to the under side of thestripper, for marking ornamental figures to guide the operator institching the figures.

This plate may be as shown in the drawing, or it may be extended so asto mark. around the line of holes F, or to make any desired figure.

Q represents one of the broad punches for punching out the holes B. Itis made concave in the punching-face, as shown in Fig. 2, in order thatit may shear-cut the goods from the pivots a to the center, and thushave the benefit of cutting in that manner without displacing the goodson the die, which would be the case if sheared in one direction only. R

represents the punches for working the small holes F'of the die-plate,to make the small perforations in the goods.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The steel die-plate A, in combination with andattached to a similarly-perforated iron supporting-plate,H,substantially as specified.
